so, im currently running an amd socket am3 platform, with an athlon II x 4 630 clocked at 3.4Ghz. i was going to buy the 1090t six core cpu for $230, but i have been offered by a friend a biostar tpower x58 motherboard, an i7 920, and 6 gigs a g skill triple channel ram for $250. im wondering if the i7 920 and board and ram will outperform my current setup in my sig, and if it will help my 2 gtx 470's in sli perform better. i was told that my athlon II x 4 630 was bottlenecking my 2 cards. will upgrading to the i7 920 resolve this issue and is the motherboard any good. he says that it has been a great board, but he's upgrading to sandybridge. and which is better the i7 920, or amd 1090t? ive seen bench marks and it looks as if the i7 pretty much keeps up with it. basicaly i want to get rid of the bottleneck, so i7, biostar x58 board and 6 gigs of g skill ram for $250, or just get the 1090t for $230? any and all opinions and facts are greatly appreciated
